Your smartphone has reached a new level of intelligence: with the help of a forthcoming iPhone feature, you’ll be able to tell when you’re going to be getting your period.
The iOS 9 upgrade will add a track-your-period feature to the HealthKit app, Gizmodo reports. The health app—which already tracks several screen-scrolls’ worth of health and fitness data—seems to be able to record how long (and heavy) your menstrual cycle is. The feature was briefly mentioned Monday at WWDC and details are sparse, but the update is billed as a “reproductive health” tracker, so it may come with other features related to fertility.
Women have used menstrual tracking and fertility apps for years; all kinds of apps exist to help maximize—or minimize—the chances of pregnancy. The extra feature, due out with the next update, will finally give women a more complete digital view of their health.
